I'm constantly amazed about how people will post private information in a public place (thus making it public information), and then complain about how they are being robbed of their privacy.
Carnegie Mellon behavioral economist George Loewenstein is releasing an interesting study on privacy behavior...
From The Linked Article:
The scientists conducted several surveys of college students, asking them to provide an e-mail address and then indicate whether they had ever engaged in a list of wayward, or in some cases illegal, activities.
In one experiment, one group of students was given a strong assurance that none of the information they divulged on the survey would be revealed. That should make them more forthcoming, right? Actually, the opposite was true. When the issue of confidentiality was raised, participants clammed up. For example, 25 percent of the students who were given a strong assurance of confidentiality admitted to having copied someone else's homework. Among those given no assurance of confidentiality, more than half admitted to it.
